1 / 44 page LM2599 www.ti.com SNVS123C – APRIL 1998 – REVISED APRIL 2013 LM2599 SIMPLE SWITCHER® Power Converter 150 kHz 3A Step-Down Voltage Regulator, with Features Check for Samples: LM2599 1 FEATURES DESCRIPTION The LM2599 series of regulators are monolithic 23 • 3.3V, 5V, 12V, and Adjustable Output Versions integrated circuits that provide all the active functions • Adjustable Version Output Voltage Range, for a step-down (buck) switching regulator, capable of 1.2V to 37V ±4% Max Over Line and Load driving a 3A load with excellent line and load Conditions regulation. These devices are available in fixed output voltages of 3.3V, 5V, 12V, and an adjustable output • Ensured 3A Output Current version. • Available in 7-Pin TO-220 and TO-263 (Surface Mount) Package This series of switching regulators is similar to the LM2596 series, with additional supervisory and • Input Voltage Range Up to 40V performance features added. • 150 kHz Fixed Frequency Internal Oscillator Requiring a minimum number of external • Shutdown/Soft-start components, these regulators are simple to use and • Out of Regulation Error Flag include internal frequency compensation†, improved • Error Output Delay line and load specifications, fixed-frequency oscillator, Shutdown/Soft-start, error flag delay and error flag • Low Power Standby Mode, IQ Typically 80 μA output. • High Efficiency The LM2599 series operates at a switching frequency • Uses Readily Available Standard Inductors of 150 kHz thus allowing smaller sized filter • Thermal Shutdown and Current Limit components than what would be needed with lower Protection frequency switching regulators. Available in a standard 7-lead TO-220 package with several APPLICATIONS different lead bend options, and a 7-lead TO-263 Surface mount package. • Simple High-Efficiency Step-down (Buck) Regulator A standard series of inductors (both through hole and surface mount types) are available from several • Efficient Pre-Regulator for Linear Regulators different manufacturers optimized for use with the • On-Card Switching Regulators LM2599 series. This feature greatly simplifies the • Positive to Negative Converter design of switch-mode power supplies. Other features include an ensured ±4% tolerance on output voltage under all conditions of input voltage and output load conditions, and ±15% on the oscillator frequency. External shutdown is included, featuring typically 80 μA standby current. Self protection features include a two stage current limit for the output switch and an over temperature shutdown for complete protection under fault conditions.
